3,895 answers about fish & aquatics
A healthy aquarium is a balanced one — water chemistry, filtration, stocking and feeding all work together, and most fish problems start with the water. This page gathers the fish and aquatics library of KinsLe Answers in one place, organized by topic for freshwater and saltwater keepers alike. Every answer is original, written by KinsLe, and tied to a real KinsLe feature.

Expect a receipt naming the exact rummy-nose species, the size of the school you bought, and its origin, together with the seller's temperature, pH, and softness values and a note that the fish were feeding and coloured up in the shop. Three similar species are sold under this name, and the redness of the nose is…
Expect a receipt giving the loach's full species name rather than just hillstream loach, the number bought, and whether they were wild-caught, plus the seller's temperature and a note on what the fish have been grazing and eating. Several different loaches hide under this one shop name, and their flow, temperature,…
Expect a receipt that identifies your clown killifish by name, states whether you bought a single fish, a pair, or a trio, and records the sex mix, because males and females look and behave quite differently. Also ask for the seller's water values in writing, especially how soft and acidic the holding water was, and…
Expect a sales receipt naming the fish by both common and scientific name, the number in your group, and whether they were captive-bred or wild-caught, plus the seller's water temperature and pH and what foods the group has been taking. For a shy, tiny schooling fish like this, that feeding and water history matters…
Yes — yoyo loaches are social, long-lived and full of individual character, so a log that tracks group dynamics is as useful as the feeding notes. Record how many you keep, each fish's favourite hiding cave, and who leads the evening patrol, because hierarchy shifts explain most yoyo behaviour changes. Note sinking…
Yes — scissortail rasboras reward a log in a very specific way: it explains losses. These streamlined schoolers jump, and a dated record of lid gaps, startling events and headcounts turns a mysterious disappearance into a solvable pattern. Note school size, where in the water column they feed, and whether every fish…
Yes — rosy barbs are active, long-lived schoolers whose size, plant-nibbling and hearty appetites are all easier to manage with dates attached. Note how many you keep and their growth, because a school of rosy barbs occupies far more tank than the small juveniles you brought home. Record foods including vegetable…
Yes — peppered corydoras may be hardy, but a log still earns its place by tracking group size over years, who is actually eating at the bottom, and the conditions that trigger their famous spawning dances. Note additions and losses, sinking foods offered and finished, and any egg-laying on the glass after a cool water…
Yes — a log is one of the most useful tools in a peacock cichlid tank, where stocking ratios drive aggression and colour, and generous feeding can quietly cause harm. Note every addition with its sex and variety, which males coloured up or were suppressed, and any fish moved out after persistent chasing. Record…
Yes — panda corydoras are small, schooling bottom-dwellers whose problems, from missed meals to eroding barbels, develop quietly at substrate level where they are easy to overlook. Note group size and every addition or loss, because pandas kept in shrinking numbers grow shy and feed poorly. Record which sinking foods…
Yes — for oscars a log is close to essential, because few pet fish grow faster, eat messier or change a tank's stocking maths more quickly. Record length estimates as your oscar grows, every tankmate addition or removal, and what staple pellets and varied foods are actually eaten versus spat out. Note appetite dips…
Yes — odessa barbs are schooling fish whose colour and confidence are direct readouts of group size and feeding, so a log captures exactly what matters. Note how many you keep, the balance of males to females, and when a male's red intensifies or fades after a stocking change. Record foods offered, from flakes to…
Yes — a light log is genuinely useful for nerite snails, because the main risks they face are slow and easy to miss: too little algae, a chipping shell or a gradual string of escapes. Note how many you added and when, the pattern type so individuals are recognisable, and whether the tank's algae is keeping up with…
Yes — for kribensis a log quickly becomes a breeding and behaviour record, not just a feeding list. A bonded pair can claim a cave, spawn in secret and emerge herding fry, so note arrivals, who paired with whom, which cave they chose and when free-swimming young first appeared. Record foods too, from staple pellets to…
Yes, especially if you keep a pair or a small group, because honey gouramis change so gradually that appetite, colour and confidence are easy to misremember. Note who was added and when, which fish builds a bubble nest, and whether a shy individual reaches food before bolder tankmates finish it. Record small offerings…
Yes — hillstream loaches benefit more than most fish from a written log, because how much they eat is hard to judge by eye. Much of their food is biofilm grazed from rocks, so note when that grazing slows, when supplemental wafers or soft vegetables are offered, and whether every fish gets time at them. Record…
Yes — ghost shrimp are translucent, short-lived, and constantly cycling through moults and pregnancies, so a log captures a colony life you can barely see directly. Record approximate numbers, berried females, and moults found, plus whether sinking food reaches the bottom before fish take it. Note any new fish added,…
Yes — firemouth cichlids flare first and fight rarely, so a log helps you judge whether dramatic displays are settling a hierarchy or signalling a real problem. Record who holds which territory, when throat-flaring escalates, and whether subordinate fish still feed freely. Pairs preparing to spawn will dig and defend…
Yes — espei rasboras are peaceful, copper-toned schoolers that thrive on stability, and a log proves whether stability is what they are actually getting. Record school size, any drift in how tightly they school, and how they take small floating and sinking foods. Note changes in lighting or tankmates, since this shy…
Yes — Endler's livebearers breed almost continuously, so your stocking is changing even when you buy nothing, and a log is the only way to know your real numbers. Record new broods, rough fry counts, and when young males colour up, plus the balance of males to females in the colony. Feeding notes matter too, because a…
Yes — dwarf rainbowfish are lively schoolers whose males spar and display constantly, and a log separates normal sparring from a pattern that is wearing one fish down. Record school size and sex balance, morning display colour, and whether every fish gets a share when food hits the surface. These small fish mature and…
Yes — discus are sensitive, social fish kept warm and fed richly, and small drifts in appetite or hierarchy often precede bigger trouble. Log who eats first and who waits, any new fish and its quarantine, and how the group responds after water changes. Because discus feeding is frequent and messy, notes on leftovers…
Yes — convict cichlids breed readily and defend their fry fiercely, so their tank can change from calm to crowded and combative in a single season. Log pairings, spawn dates as best you can judge them, and how many young survive each batch, because today's fry are next month's stocking pressure. Note feeding too,…
Yes — clown plecos hide by day and feed largely at night, so without notes you may go weeks without knowing whether one has eaten at all. Log where each fish's favourite driftwood spot is, what sinking food and wood you provide, and when you last saw each individual at the glass. A pleco missing from its usual haunt…
